Note.—Suṣumnâ=A principal ray of the Sun. For one night the Devas, the Piṭris and the Ṛiṣis worship the Moon. From the beginning of the dark fortnight the Moon turns back, wanes and becomes dull; His digits decline owing to His nectar being drunk up day by day. 33330 Devas drink the lunar ambrosia. The Moon thus declines during the dark fortnight and waxes until He becomes complete in the bright fortnight. Thus, drinking the nectar, the Devas, at the end of the fortnight, go away elsewhere on the Amâvasyâ (dark) night when the Pitris come to Him. When the still small portion of the 15th part of the Moon is left, they drink that in the afternoon on the next day for a brief period of two kalâs and go away after the completion of this dark fortnight. The Saumyâs, Vahriṣadas, Agniṣvâttâs and Kâvyâs, are the Piṭris. Those who preside over the year are known also as Kâvyas. So also the Dvijas performing good works can become Kâvyas. The Saumyapitrạs are rigid ascetics. Vahriṣada, Saumya and Agniṣvâtas are the wellknown threefold Pitri creation who are recognised as twice-born (Brahmanas).—61-70.
